When do we lose our milk teeth?
The average person has two sets of teeth, one after the other. The first is the baby, milk, or deciduous set. Even before birth, teeth appear as tiny buds below the gums. They begin to erupt, or show above the gum from the age of a few months. By the age of about three all 20 first teeth have usually appeared. In each half (left and right) of each jaw (upper and lower), there are two incisors, one canine, and two molars.
From about the age of six years, the first teeth start to fall out. These are replaced by the adult, second, or permanent set. First are usually the front incisors and the first molars, at around seven to eight years. Last are the rear-most molars, or wisdom teeth. They appear at 18-20 years of age in some people, while in others they erupt at 40 or 50 years of age – and sometimes they never appear. In each half of each jaw, there are typically two incisors, one canine, two premolars, and three molars, making a full set of 32 teeth.
Fact File: Your back teeth are bumpy on top. You can feel it. They work together, grinding food between the bumps. These grinders need regular and careful cleaning when they finish work. Food often sticks between the bumps. |
